 ;)  Speedtest was a laugh wasn't it.  Thanks though for the reassurance, since the last 3 months have seen some wierd results, including that dip and climb back out.  I am a fair distance from the exchange and didn't expect any better than around 2meg, but the latest recovery to 4.4meg is certainly welcome.

 :wall: :hmm: :mad: :'(



Been like this now for a fair few hours and seems to have reset itself 8 hours ago - we didn't have any power cuts.

Colin,have you run the BT speedtester to see what results you get.

Here they are, and also a sample of the past week of monitoring by Samknows (I have one of their monitors on the line):

It looks like your line may have become noisy :(
Its lost the connection at some point recently and judging from your stats now, its had to sync at a lower speed to be able to cope.

Unfortunately the lower sync speed will now also land you with a lower IPprofile which is going to affect your throughput.

Time to get routerstats running on the line to monitor the SNR to see if it can pin-point any patterns in the noise.

I now have routerstats lite running is that OK?

Noise margin is currently (only been running 15 minutes so far) sat at 12 dB.

Yes should be fine - its your SNRM that needs monitoring.

Since I have a BT Home Hub v.1 am I right in assuming that only the Lite version will run OK?  CORRECTION - The noise MARGIN is 12dB

See attached

I'm not sure what your PDF was meant to be, but all it shows is the up and down noise margins. If you want to attach a graphic, a .gif or .png is usually more effective. (Hope you don't mind my saying this :) )

Whoops! - you're right, I put the wrong attachment on - senior moment  :-[

Since then, this occurred  see png attachment

[EDIT] and the BT Home Hub shows one loss of signal (local) in its detailed link information page.

Did the router record that loss of signal at the time where the Routerstats graph shows the brief dip, or was it unconnected? The reason I ask is that Routerstats and RS-Lite do sometimes display a glitch like that, but it's not a real connection drop but merely one sample which RS failed to get from the router. If the connection speed was unchanged, I think that it's likely to be the latter.

The router shows one loss of signal (and only one) that occurred around the same time - it is on another floor from where I work and, naturally I am monitoring it through the network.  Interesting though, the SNRM has now gone down to 11.5

[EDIT] - being a BT Home Hub, I can't get at the stats to look at timing of the loss.

It appears unchanged at 2528 so certainly just a missing data point.
It behaves like that for me; I sometimes use DMT to check for certain that it's not done a resync at the same speed, but it never does.

Yes, the speed of the recovery (only one sample missed) also supports that view.
